Product Details

Sunburn! We have all experienced the pain and misery of overexposure to the Sun’s intense “heat.” Sunscreens applied to the skin shield us from the damaging ultraviolet rays. Students create their own sunscreen from one of eight prescribed formulations of lotions and sunscreen chemicals. Once the sunscreens are made, students use a spectrophotometer to determine the absorbance of ultraviolet light by their sunscreen. The results are compared to determine the most effective sunscreen.

Complete for 30 students working in pairs. A spectrophotometer is required and available separately.
